PRooEss oF GENERATlNG PRODUCER-GAS.

To-all whom it may coriccrn:

Be it known that 1, MAX F. MANGELS York and State of New York, have invented certain new and useful Improvements in This invention relates to process of generating reducer gas by the passage through a bed o ignited fuel of s eciallytreated prodnets of combustion, ELIE has for its object the production of combustible gas low in. hydro genand containing only a modicum of nibon dioxid to carbon monoxir which gas with. whatever nitrogen may accompan it is carried to the place of consumption an utiiized for heating or generation oflpower etc.

Y One embodiment of my-invention anda preferred form thereof isdepicted in thenccompanyine diagrammatic drawing which I latter.

In the drawing 1 is a gas producerof'a suitable type. i

A is a scrubber for cooling and cleaning the gas...

4 is. a gas engine or internal combustion motor, having an exhaust pipe 51eading to the diffusion chamber 6. The diffusion chamber is made of some semi-permeable substance and I prefer to pro )are it in thefollowing bent ofdamask or linen and wrap it several times around a tube of stiff wire screening and sew it firmly to the I re are a com 'iound by dissolving one poun oi aluminium rcsinate and one pint of Chinese wood oil in three gallons spirits: of turpentine. The cloth is impregnoted with this solution, dried and aged for at least onehundred days to acquire the requisite .orosity an'd difl'usive action. It is then rca y for use in the manner to be here- Specificaition of Letters Patent.- Appiication filed April 24, 1906. Burial No. 313,478.

inafter specified. Fromv the diffusion tube 6 a pipe 7 leadsto the'producer 1. In pipe 7 isanairinletS.

9 andlO are dampers or valves. 11 is an outlet pipe for surplus productsof explosion.

.he operation is as follows :-A deep bed of ignited fuel, suchas anthracite or coke or lignite or soft coal etc. is formed in the pro ducer 1. Air is introduced throu h the inlet 8; the damper 9 bein open an 10 being closed for a time until the tire is of the proper tern erature. 1U then opened and 9 is part y or wholly closed. The as produced passes through the scrubber and enters the engine, being there exploded with air in the usual manner except that high compressionis used as the 'gas ls'i'ree or practiw cally free from hydrogen. The exhaust gases in part pass away through; the pipe 11, but a portion are entered into the diffusion chamber Where part of the nitrogen is removed by the difl'usive action of the membrane. Deprived of this. nitrogen the exhaust gas is made. richer in carbon dioxid and the treated exhaust gas is entered with airinto the roducerchamber. Usually I enter the aft purifier and under the grate but under certain circumzones of the fire ed may receive exhaust gas of-the same composition.

For continuous operation I make up a mixture of exhaust. gas and air in such pro. ortions as to prevent the fire bed from clin ering and yet maintain an efficient gasifying temperature. When however I operate on the intermittent plan, similar to water gas manufacture, I admit only air through the pipe 7 and heat the fuel her to incandeseence. Then I shut off the air and admit products of combustion until the temperaturelof the producer falls to a low oin't' when the air blow.

is repeated, etc. T 1e roducer maybe up draf t or down draft an( may be'operated on the suction or pressure principle. Fan blowers or positive pressure blowers or'jet inductors may be used for causing the flow of gases in the desired direction. Two or more producers may be joined in tandem or otherwise and the gas produced by an 11 draft in one may be'further enriched. in car on mon'-' oxid by downward passage through anotherproducer, as will be evident to those skilled stances I introduce the exhaust gas at different levels in the reducer so that the various .in the art to which this invention appertains tainin only one combustible element; is es pecial y suited for gas enginesand-permits'of a compression of 200 pounds'or more yet I do not limit myself to such ap lication as the invention is'of great value in l feating furnaces and the like and I lay claimto its ap lication in thismanner, The scrubbing an; urifying apparatus is unnecessary in dlrnace work. v.

'I am aware of the use of gases high in carbon dioxid from. lime kilnsetc for gas roducer operation and I do not claim suc as my invention. I believe however that I am the first to discover that the eater diffusive power of nitrogen over car on dioxid permits of its removal to a'con'siderable extent from products of combustion by passage thereo through suitable diffusion a aratus and that such a treated gas isusefuor gen- Y mum of carbon monoxid is desired. The

erating a combustible gascontaining a very high percentage of carbon monoxid. g

The intermlttent method above'described is preferable when a gascontaining a maxicost of generation is however slightly greater than that ofthe.continuousmethodflwhich, be it said, affords a 'gaslof excellent quality for gas engines. 1 V a; For gas engines employed inimarinei propulsion this invention is eminently adapted.

If the gases in the diffusion tube'are under considerably diminished pressure; as sometimes appens, a jacket (not'shown) maybeplaced aroundthe tube and suction applied to aidvin the passage of the nitroge through the semipermeable Walls of the tube.
